Coulomb’s law calculator

Coulomb’s Law states that the force of attraction or repulsion between two charged particles is directly proportional to the product of their charges and inversely proportional to the square of the distance between them. The mathematical statement of Coulomb’s Law is:

$$F=K\cdot \frac{q_1q_2}{r^2}$$

where:

• F represents the electrostatic force between the two charged particles.
• k is the electrostatic constant or Coulomb’s constant, which has a value of approximately 9×10^9 N⋅m^2/C^2
• $q1,$ and q2​ represents the magnitudes of the charges of the two particles.
• r denotes the distance between the centers of the charged particles.
